I've been shooting my first rolls of medium format with a Yashica-Mat (not the 124). The first roll had light leaks, so I added foam light seals (I'm aware that this isn't strictly necessary for these cameras, but I couldn't figure out a better way to stop the leaks!). I've now shot and developed a second roll, with some surprising results:
Frames 1-3 seem to be fine.
Frames 4-9 are blotchy, where the blotches are on the negative.
Frames 8-9 look like they have light leaks,
Frames 10-12 seem to be fine.
This leaves me with two questions:
1) What are the blotchy marks on frames 4-9? I should say that I was using developer that is way past its use-by date. But I guess this isn't the problem, as only half of the frames on the roll are affected.
2) Why do only frames 8-9 have light leaks? It might be significant here that there was a significant gap between my shooting frame 9 and frame 10 - a couple of months where the camera sat on a shelf in my living room. Could it be that these are "slow" light leaks, analogous to a slow puncture? I've no idea whether this is a real thing!
For further info. This is a roll of 120 FP4 Plus (125 iso), developed in HC110 (dilution B) for 7.5 minutes at 20 degrees celsius. Continuous agitation for first 30 sec, then 5 sec every further 30 sec.
All feedback gratefully received! I'm trying to weigh up whether these are problems that I can resolve and whether it's worth the time. I'm thinking I should perhaps just invest in a medium format camera that doesn't come with these problems!
